Fillers for resins.
URE FIL fillers disperse easily in Smooth-On materials. They can be added in different proportions to achieve a variety of working properties and effects. Some fillers are designed for cost-savings, others are designed for specific casting effects or improved physical properties. Other URE FIL fillers are designed specifically for thickening materials for brush-on or trowelable application.
URE-FIL 3 Ceramic Filler to Reduce Cost of Casting
URE-FIL 5 Filler for Creating a Wood-Grain Effect
URE-FIL 7 Urethane Filler for Dimensional Stability
URE-FIL 9 Fumed-Silica Based Thickening Agent
URE-FIL 11 Fiber Filler for Urethane and Silicone
URE-FIL 15 Micro-Balloons to Reduce Casting Weight

URE-FIL 3
Use Less Resin, Lower Cost. Ceramic filler which is added to urethane resins and castable epoxies to reduce cost. Recommended starting mix ratio is 1A to 1B to 1 part URE FIL 3.
URE-FIL 5
The best choice for creating a wood grain effect. Note: your mold must reflect the wood grain pattern of the original model. Mix 1 part filler with 1A:1B of Smooth Cast 320 resin and cast into mold. After demold, apply wood stain or shoe polish to casting surface to bring out wood grain effect.
URE-FIL 7
Improves dimensional stability in urethane resins and castable epoxies. Ofen added to materials to make them flame-resistant. URE FIL 7 can be mixed with Smooth Cast 325 and SO Strong color tints to create marble effects. Recommended maximum mix ratio is 1A:1B to 2 parts filler. A mix ratio of 1A:1B to 3 parts filler will make the plastic trowelable, but the cured plastic will also be brittle.
URE-FIL 9
Fumed silica based thickening agent primarily used with liquid urethane and silicone rubbers for brush on moldmaking applications. URE FIL 9 is added in small amounts to the mixed rubber until the desired viscosity is achieved. URE FIL 9 can also be added to liquid urethane resins to create casting effects and to thicken the material for trowelable casting applications.
URE-FIL 11
Fiber based filler that can be added to Smooth On urethane and silicone rubbers, urethane plastics and epoxies to thicken for brush on applications. URE FIL 11 can be used with all Smooth On silicones, including those which do not respond to THI VEX such as Ecoflex 00 30 and Mold Max 40.
URE-FIL 15
Micro balloons that can be added to Smooth On urethane plastics and epoxies to create very light weight castings. Castings which float on water can be created by using proper proportions of URE FIL 15. A casting resin filled with a large proportion of URE FIL 15 can be described as a syntactic foam", non expanding foams which are stiffer, stronger and more water resistant than water blown expanding urethane foams of the same density.
